On our website you can enter your ZIP code, then you can receive an analysis of all dissolved contaminants in your water. Until now we are not able to provide that instant service for microbacteriology, but as a rule of thumb: if you live in a low mountain range or your water supplier draws the water from a river or a dam, you should definitely consider installing a drinking water treatment system. In low mountain regions, the rocky soil does not have sufficient filtering effect, so that pathogens from the surface are carried into the drinking water conductors during heavy rain events. If the drinking water comes from rivers or dams, the water may contain pathogens as well as drug residues and hormone-like substances that are discharged into the water from sewage treatment plants. Often these are not recorded in drinking water analyzes!
